Modem Help Please!!

[ShaggyDog]

I have been unable to connect to dial-up with the T60 modem - unfortunately I need the dial-up where I'm going.
Tried everything (all updates/Bios current), uninstalled & reinstalled modem driver, dial-up account active, tried different service provider, Lenovo help stumped, local guys stumped.

I get dial tone, connects to server, then Error 720 - unable to communicate with remote server - check network settings. Modem seems to work but no connect. Tried Fax feature thru modem - it worked send & receive. Compared settings with old Toshiba that works - all the same, however could not find comparable "allocated resources" to match up.

I realize it may be impossible for anyone to troubleshoot from a distance, but ONE THING that seems to be missing is the "allocated resources" - there are none listed.

Hoping someone can look up what their T60 (2007 - 62U) CXT modem, says for "allocated resources", so I can eliminate or fix that.

START
CONTROL PANEL
THINKPAD CONFIGURATION
click INTERNAL MODEM
click ALLOCATED RESOURCES tab

see what, if anything is listed under "Resource Type" and "Setting"

(A Lenovo troubleshooting memo says certain I/O, DMA & IRQ resources should be listed - but it doesn't specify a T60)

Thanks to anyone that can help.

Have you run PC Doctor?

I do not have a T60, but my T42 does have a Conexant modem (ThinkPad Integrated 56K Modem) - which could be different than yours.

The resources my modem uses are:
IO address 2400-24FF
IO address 2000-207F
IRQ 11
Under Modems in Control Panel it shows that it uses COM3.

This does not sound like a modem issue, this sounds more like a protocol issue probably having to do with the PPP protocol and tcpip and/or the winsock. It's been so long since I used a modem to connect to an internet provider that I'm probably not going to be much help without actually sitting in front of your T60 but here are a few suggestions.
Turn off your firewall.
Take a look at this MS article, http://support.microsoft.com/kb/811259/en-us
Seach the microsoft knowledgebase for the keyword "error 720". Windows 2000 fixes in the knowledgebase may apply.
The helpdesk of some internet providers may actually be able to help you as they work with dialup issues all the time.

Again, I don't think this is a modem issue.

Good luck

Can you hear the modem dialing the number? (Try setting the modem to use Tones/Pulses option).
Disable Wi-Fi card
Check if TCP/IP is enabled and configured to receive automatically an IP Address

[GomJabbar]

I just looked at ThinkPad Configuration > Internal Modem > Allocated Resources.

What is listed is:
IO address 03E8-03EF
IRQ 7

This is the COM port resources, not the modem resources. As I stated earlier, the modem resources are found in Device Manager. You do need both the modem and COM port resources available for the modem to work.

Oddly, I just noticed that my Sierra Wireless AirCard uses the same COM port resources listed above, but is reported to use COM9, while the ThinkPad 56K Modem uses COM3.

Check in Device Manager for what is using the above IO address and IRQ (look under View > Resources by type). AFAIK, if another device is using the same resources, your modem will not work. You can temporarily disable the other device to free up resources. Realize of course that your T60 could be different than my T42.

Tx for all the replies,

Pianowizard:
"have you run PC Doctor?"

- yes and modem comes back fine.

Benottomex:

Yes, dial-tone everything works fine, TCP/IP is enables & auto to receive IP.

How do you disable the Wi-Fi card???

GomJabbar:

I'm leaning to the fact I have NO allocated resources listed, whereas I think I should have some. The IR port has the ones listed that should also be on the internal modem (according to Lenovo troubleshooting)-

IRQ3
I/O 02F8-02FF for the modem

. I disabled the IR port, but the internal modem, still showed blank on allocated resources. Seems all the other device tabs have the ability to configure the resources except the modem!

Does anyone know how to allocate resources, or if you can't, what should be allocating the resources and isn't? Nowhere can I find out to do it - they just say check that they are listed.

SteveG47:

Am going to try the article you quoted - first time I saw the Error 720 listed. I tried the Microsoft troubleshooting and it skipped from Error 719 to 721!

All firewalls were off & limited expertise from the provider.

Troubleshooting Winsock2 right now.

[GomJabbar]

To reallocate resources to the modem, try the following. In Device Manager, disable the ThinkPad Fast Infrared Port, then go to the modem and uninstall it. Now reboot. On boot up, Windows will find the modem, install the drivers, and should allocate the resources.

To reallocate resources to the modem, try the following.

Gomjabbar's advice is right on in my opinion. But I would first delete your current dial-up connection in Network Conections. Then do as Gomjabbar advised. After reinstalling the modem and drivers create a new dial-up connection using connection wizard, or however you are confortable doing.

Make sure that your dial-up connection Networking properties has the "Internet Protocol (TCP/IP)", and "Client for Microsoft Networks" Checked. Don't check "NWlink IPX/SPX/NetBIOS Compatible Transport Protocol". The "Type of dial-up server I am calling:" Should be set to PPP.

Sometimes (Has happened to me once) TCP/IP has become corrupt and needs to be reset. I would do this last if all else fails.

Click Start, then Run. Enter the following in the Open text box:
netsh int ip reset resetlog.txt
Enter and restart computer.

Being ol'sku has its uses. I would get the modem operating correctly in terminal-mode in Windows Hyper Terminal first. Connect to your dialup ISP manually just to see that it isn't a hardware problem (and it probably isn't). AT commands are your friend.

[claudeo]

I would first try to connect to another dialup server to detect whether that is the problem. A common issue is an error in the login or password -- we set this up in a dialup connection and then forget about it. Last week I was at a friend's and he gave me his dialup login info -- would not work. Then I realized that the correct login was the login he gave me plus "@provider.net".

If you remove the modem using device manager it may not be rediscovered automatically. That's another thing I discovered to my chagrin when some app installation caused all my audio drivers to disappear -- and the modem uses those for some reason, so the modem disappeared as well. That was bad news because I was stuck in the boonies with only the dialup connection available. I managed to find the drivers and reinstall them, after some trial and error, from the local files in the C:DRIVERS, but that was a real PITA. I would recommend that you do *not* uninstall the modem if you can avoid it, or if you do so it should be the last resort. The error does look more like a connection protocol error.

I travel A LOT around the world and have had the same issue.

My guess is that it's the difference in V90 and V92 using the modem. I CAN use the modem in most of the EU, hut have trouble in Central America for instance.

My basic yet effective solution: Get a PCMCIA modem card

I bought a very very cheap one, which actually works in the poor countries and use the internal for the rest.

Good luck!

Hello & back on the forum. I went back with IBM help and they concluded a reinstall of windows was necessary (did this before I saw the option GomJabber suggested re: allocated resources). I had back-ups in place so IBM walked me thru it. I must say with the ThinkVantage option to restore to factory box setting, it made it easy. No glitches at all and lo and behold, modem dial-up worked perfectly right from the start. I have pretty well got all programs back on and still works fine.
I tried to figure out what has changed but can't see anything obvious. Under allocated resources, still nothing listed for modem, BUT it works fine. IBM figures some corrupted file in 32, possibly related to a bluetooth device.

Thanks to everyone for the help.
